摘要

This study reports concentrations of BDEs 47,99,100,153,and 154 in outdoor air [median SPBDE (sum of BDEs 47,99,100,153,and 154) = 18 pg m~(-3)] in air from a range of office and home indoor microenvironments (median SUMPBDE = 762 pg M~(-3) and vegan and omnivorous duplicate diet samples (median SUMPBDE = 154 and 181 pg g~(-1) dry weightfor vegan and omnivorous diets,respectively).Median daily human exposure to SUMPBDE via inhalation is 6.9 ng/person and 90.5 ng/person via diet but the relative significance of these pathways may vary considerably between individuals.Median concentrations in indoor air were higher in workplace (SUMPBDE = 1082 pg m~(-3)) than in domestic (SUMPBDE = 128 pg m~(-3)) microenvironments,and substantial differences in concentrations in air from different rooms in the same office building were found.When data from the only mechanically ventilated room was excluded,a significant positive correlation (p < 0.001) was observed between PBDE concentrations and both the number of electrical appliances and polyurethane foam-containing chairs.Concentrations of SUMPBDE and BDEs 47 and 99 were significantly higher (p < 0.1) in omnivorous diet samples than in vegan diet samples,implying that while plant-based foods contribute appreciably,higher exposure occurs via ingestion of animal-based comestibles.
